Wheel-gage.



To all 1-Hmm,v it muy concern);

Be it known that I, JOHN DEMAR'EY, a sub- Armour avenue, Chicago, Cook county, State 'heel-Gage, of which the following is a speciiiwtion. My invention relates to an improvement in wheel-gages to ascertain whether the boxes in carriages, buggies, and other. vehicle-wheels are set true, i

` The object of myiniprovement is to have that part of the gage which is placed in the box adjustable, so that either end thereof' can be' extended in diameter without an)` matet. i rial change of the other, so that the gage can `be easily adjusted to t in any size and taper of axlebox, and alsolhe arm or other part of the gage which extends out over vthe wheel when the gage is in ase to have that adjustaccording tothe height of the wheel, and also i adjustable, so that' the point end thereof can l l Y be lowered and set in any required position 2 5 to bring it in contacta-ith the tire or rim of the wheel. I attain these-.objects lby the mechanisnzr illustrated `iuftlie accompanying drawings, in which- Fig. 2 is a vertical view of that part designed' r to 'fit in the box, the dotted lines showing the shape to which it Vmay be extended at the `lower point. Figf' shows a vertical section of the same part'extended at both ends, one r 35 o'fl thethree ribs with the attached spring and braces removed. Fig. -L shows a transverse section. Fig.. 5 is a Vvertical section showing the center rod and tube through which it passes. Figs. 6 and are point views of con-ic washers. Fig. Sis an end View of `the central tube. Fig. 9 is a top view of guardv and rib to which itisattached. Fig. 10 isaside view of the arm.

"A is a. rod, to which is attached or riveted 45 on the lower end the conic washer, Fig. 7. i The rod A passes through a tube B and has r an annular grooved nut C, which is threaded i to iii;V on the topend of rod A. The said conic l washerals'o `has an annular. groove a toA receive the lower end of the tube B. One end of the brace Dis fitted into a' groove in the conic t Washenlig 3, b andlFig.- 5, b. The other end NITED SLATES ,.Pa-

` Application neuw 1e. i902. serial s. 111.941. flamand ject of the `King of Italy, residing at No. 1923 beingfastened to the tube ll by a screw, The 5of Illinois, have invented a new and useful i able, so that it can be extended or shortenedV l Figure 1 is a `view of the gage when in use.

TENT 7 i' GFF-ICE? 1 is hinged ro the rib E, Fig. s. Thelow'erend of the fiat spring passes under the pin() and under the band F, the said band and spring upper end of the spring is hinged to the rib E with a pin c?. The brace R is hinged to the rib E with-,a pin e. The top end thereof is fitted into a groove or socket in the conic washer Fig. 3,1'. The nui G is threaded to it on the tube B. By screwing it down it presses on the conic washer, the washer pressvingon the braces causn g them to extendflfom the center. (Shown by dotted lines in sectional view, Fi 5 y.) The nut C being screwed downward presses against the tube B and forces the conic washer, Fig. 7, and h upward, which acts upon the lower braces, causing them to extend from the center. The tubeB when the combination is closed does not reach the bottom in the annular groovein the conc washer enough spacebeing left to allow the washer operati-ng the braces being forced upward to obtain the extension required.`

The description given of the combination of the rib, spring, and braces constitutes one part only, there being in the'whole combination, when all the parts are together, three parts exactly alike. v

Fig. S is an end view of tube B, showing the grooves cut therein to allow space for the braces when the combination is closed. (Also shown in Fig. 3 7'11.)

J, Fig. 3, is a device threaded and screwed on tube B and set by a screwj. T is a device passing through J and is fas tened by nut and washerk passes through the aperture in T, Fig.4 2, and is set b v the washer and nut f I. The rodL. 'passes inside of the tube K and is. set and held in place b va band passing around tube K and a screw passingthrough the laps of 95 the band, the tube K being slit to allow conf,- traction by operating the screw inthe band, Fig. l1,0 m, sectional View of iband and screw,

I is a device fastened on the rod L, to which -the point-rod is hinged at i. `The spring 0 is fastened to rod L and rod N. The screw jipasses through the rod L and by operating it forces the point of ,rod N 'down to any desired position. The break u in tube K and The tube K 9m `and also i,to give the gage atx-ue bearing.

'9, is a top vieu-'showing the manner in which if itis fastened tothe rib.` P, Fig'. is a full vertical iievr guard. The guard can V beslid'upn' downto L anydesired height by releasing and fasten ing thescrew. (See Fig.l 9 auddorted lines`A on rib' E, Fig. 3.) The use of the 'nardisl te prevent the 'gage getting too far intotlze bok The operation of iiiyxvheel-gage is as f0l The guard is moved on the, rib till it bears against the end of thebox. By releasing the serein the chimp-band mt'nc red L can be extended from lthe tube K to the desired" lengt-h'. t The nut on the device T can be released and the arm bronght'down' with the point` in proximity to the tire or I'imof the wheel, and the screw j can be operated to small variation desired, the gage being thus adjusted, and by turning it around in the axle-bo x.-t l1e point. of the gage will indicate a true' plane at a rightanglc to the axis et the box.

Vhat I claim as my invention, and desire to secure by Lex-1ers Patent, is- Y The combination in a wheel-gage adjnstable, and composed of the following devices and means so that it can be extended in diameter to fit various sizes and taper of axletica-ed, the other endet' the rod being thread- "ed and fitted 'wh' a nut; a tube through `being hinged to the ribs hereinafter: men
